Application filed April 22, 1922. Serial No. 555,952.

To all whom it may concern:

Be known that I, EDWARD F. DUDLEY, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements Mechanism, of which the following is a specification.

This invention relates to'printing presses and more particularly to feeder operating mechanism thereof.

One object of the invention is to provide simple, reliable and efficient operating mechanism for feeding sheets of paper or other material from the stock pile progressively to the printing mechanism.

Another object is to provide driving mechanism for feeding sheets, which mechanism provides for clutching and declutching certain of the motiontransmitting parts for accommodating the feeder frame in its normal operative position and in its inoperative position when it is swung away.

Another object is to proyide feeder operating mechanism adapted to-meet the various requirements for successful commercial use.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheets of drawings,- in which-- Figure 1 is a fragmentary side elevation of a printing press'embodying my inven tion;v

Fi'gure 2 is a fragmentary top plan view of the same printing press;

Figure 3 is a, detail sectional view taken in the plane of line 3-3 of Figure 2;

Figure 4 is a detail sectional. view taken.

' in the plane of line 44 of Figu're 3;

Figure 5 is a detail sectional view taken in the plane of line 5-4) of Figure 2;

Fi re 6 is adetail sectional view taken in the p ane of line 66 of Figure 2; and Figure 7 is a detail view, one part bein in sect-ion, and taken in the plane of line 7 of Figure The various novel features of the invention wi1l-be apparent from the :following description and drawings, and will be articularly ointed out in the appended clalms.

Referring t o I it will be noted that I have disclosed my invention in connection with a vertical type r of printing press, includinga main frame 10 in- Printing-Press the figures of the drawings,

upon which a way-frame 11 is mounted. A feeder frame 12 is pivotally connected by a rod 13 to a bracket 14 secured to the wayframe 11 and to a bracket 15 forming a part of the main frame 10. Rotatably mounted 1n the main frame 10 and drivenfrom any suitable source is a shaft 16 on which 1s mounted a disk 17 having a cam race 18 for controlling the movement of oppositely arranged feeder arms 19, only one of which 26 is a laterally extending roller 28 which moves in the cam race 18 as the disk 17 containing the cam race is' rotated. From the mechanism above described, it will be appreciated that as the disk 17 is rotated, the cam race 18 transmits a reciprocatory movement to the feeder arms 19 or carrying sheets of. material from the feed pile 20 toward the cylinder .of the press. It is desirable at the time of make-ready and at other times to swing the feeder frame on itsv pivotal shaft-.113 away from its normal operative osition. 'To do this, it is necessary to provi e a specialseparable connection between p)arts of the operating mechanism carried y the main frame structure and the feeder frame. I

Referring particularly to Figures 3 and 4, it will benoted thatthe member 22 has a pocket 29 containing a spring 30 which oressesforwardl atongue 31 or one part of a clutch'whicli is mounted upon a stem 32 against which the spring 30 presses.

Cooperatingwith the tongue 31 is a second 34 by a key 35. One end of the shaft 34 hasa groove aligned with that of the groovedmember 33 to complete said second 1 clutch member. the feeder arm 19, so that it is seen that there Secured to the shaft 34 is is a releasable clutch connection, between a the shaft on which the feeder arm is mounted and the driving member 22 which receives its motion from the cam 18.

- this cam 37 is a roller 38 mounted in one end of the arm 39 of a bell crank lever 40 having thepin 27 as its pivotal center, the other arm 41 of the bell crank lover having-pivotally connected thereto one end of a link 42, the other end of which is pivotally connected at 43 to a collar 44 loosely mounted over;

the flanged head portion 45 of the member 22. Pivotally connected to an intermediate portion of the bell crank lever arnr41 is a rod 46 larpund which is mounted a coiled spring 47 'which yieldably holds the roller 38 in engagementwith the cam 37 ..lt,,is

apparent, therefore, that as the cam disk 17 is rotated the collar member 44 is given a rotary oscillatory movement about the member 22 as a center. This motion is transmitted to the suction gripper shoes 36 for causing the latter to dip into engagement with the top sheet of material the pile 20 and for lifting same pre aratory to being fed'progressively away rom the feed pile. The collar 44 forms one part of a clutch. The-other part takes the form of a collar 48 which is loosely rotatably mounted upon the member 33.: The collar. 48 is provided with a projecting pin 49' (see Figures 5, 6 and 7) which passes into an opening 50 in the collar 44 whereby the parts are locked together. Preferably surrounding the shank of the pin 49 is a spring;

51for permittingtlie pin 49, to move rear- ,ations of the invention falling within the wardly if the same should engage a part other than the opening ofjthe collar 44.

These; parts, however, normally register with respect to each other when swung around into position, but in any event after they are swung into position with respect to each other they may be given a slight relative rotative movement for bringing the pin 49 and opening 50 into register if they arenotin register at the time of bringing the collars 44 and 48"together. It will be understood that the clutch parts 44 and 48 are separated from each other when the feeder frame and its bracket 12 are swung away from the main frame as indicated in dotted lines in- Figure 2-. Upon such rearward swinging movement. of the feeder frame and its bracket 12, not only is the clutch part 48 swung-away from the clutch part 44 for disconnecting the members which transmit a dipping movement to the suction gripper 36, but also the clutch member 33 is withdrawn from the clutch member 31 for disconnecting the parts which normally transmit the oscillatory movement to the feeder arms 19. Following the connection from the'elutch member..44 to the suction gripper 36 it willbe noted that formed integrally with the collar clutch member 48 is a bracket 52 having a cam groove 53 thereinin which a roller 54 rides. This roller is mounted upon a lever 55 pivoted upon a stationary support 56 located at one side of the .laracket 52. To the opposite end of thelever-55 is pivotally connected a cofinect-ing rod 57, the upper end of said connecting rod being pivotally connected to an arnn 58 secured to a pin 59 rotatably carried in a bearing portion 60 at the upper end of the transfer arm 19. Secured to the opposite end of the pin 59 iis an arm 61 which -is"connectedto the suction-shoe unit 36. It is apparent, therefore, that as the roller 54 rides to and :fro in the cam race 53 as the bracket 52 is oscillated, that-the suction gripper unit 36' will be..dipped into engagement with the top sheetwof paper and then be raised out of engagement with the pile for the purpose stated.

- A spring 62 surrounding the rod. 57 is adapted to assist in giving the suction gripper 36 its dipping action down into engagement with the top sheet of material. In this connection, it will be understood that when the rod 57 is in its lowermost position on the arm 19, the spring 62 is compressed, so

that as the cam 53 causes the rod.57 to 'rise to give dipping action to the gripper 36, the spring 62 assists ins-making the 'action more positive. A spring 63 is employed for yieldably holding the bracket 52 and, accordingly, the collar 48 in thelimit position, shown particularly in Figure 1.

It is my intention to cover all modificaspirit and scope of the following claims.
